CORNCRIB OR THE LiKE Filed Oct. 15. 1926 Patented June 10, 1930 CARL OZBERLIN, or MANSFIELD, OHIO coRNcnIB on THE LIKE Application filed. October 15, 1926. Serial No. 141,703.

1 kThis invention relates to corn-cribs or the It is well-known to those skilled in the art of the manufacture and use of corn-cribs that the construction and type of corn-cribs-now in use have as a part of; the construction a metal ventilator piperunning from the'bottom of the crib out throughthe top and have attached to the ventilator pipe a ventilator 10 which is operated by natural forces, that is by suction producedby action of wind across the top of the ventilating shaft by wind pres sure or temperature differences.

It is further well-known that to provide means for allowing the air to permeate and flow through the grain such as corn or the like that the most efficient use of the cribfor the purpose intended is to have the vtopfmade imperforate and thoroughly sealedor closed allowing the air to pass through the walls of the crib below the toplthrough" a series of apertures formed in'the wall thereof from the bottom to a; point just below vthe lower portion of the top of the crib or the like.

It is further well-known to the users-of corn-cribs and the like that the ventilator pipe is usually made of sheet metaljand that the use of's heet m'etal for constructing a ventilator under certain climatic conditions 0011'- denses the moisture in the air on the metal,

permitting the moisture as condensed to come in contact with grain or the like su'rround ing the ventilator pipe, keeping the same insoggy, wet and 'damp condition which has a V deleterious effecton the grain or the produce stored therein, resulting in spoilage .of the grain especially with respect to early or soft corn which when housed therein contains a 40 when brought in contact with the cold surface of themetal ventilator pipe and" tends to keep the corn surrounding and adjacent to the ventilator pipe in;,a dampened and unventilated, condition which eventually, results in spoilingand decaying the corn moreor less. 7 1 It isvfurther well-known that it is more or less diflicult to provide means for permitting the air to flow from the outside of the crib walls to a point in close proximity the w high percentageof moisture and is condensed proximity to the ventilator pipe keeping the metal ventilator pipe to dry and ventilate the corn which is in close-proximity to the ventlator pipe so that it will dry adjacent or .near to the walls of the 'crib uniformly with I the other grain in the crib and permit the curing process to take place to prevent the spoilage thereof. v It is further well-known that metal when used as a ventilator pipe has no properties of absorbing or sucking in the condensed moisture of the air but tends to cause condensationand it is therefore diffieultto ventilate and dry the corn near the ventilator by the process of evaporation when a metal veny tilator is used. n l

The primary object of this invention is to provide means for using material in the construction of a ventilator pipe that has ab sorbent qualities to absorb more or'less of the moisture in the air and which is made of wood or the like, (preferably) of the character' and kind ofwood known as pine, cypress or the like that does not tend to cause condensation. h

A further object of the present invention is toconstruct va ventilator pipe of a series (preferably) of wooden slats having openings' provided therein, or spaced apart from each, other top'rovide openings to permit the air to permeate or enteritherein and to close the upper portion thereof from' a point adjac'ent tothe bottom of the top thereof to preventair from entering above the" bottom of the roof.' I

"A further object is to provide a ventilator upon the ventilator pipe which is operated by natural forces such as wind suction, wind pressure and temperature differences. 7

A further object is to provide a ventilator pipe and construct same of such material, that it will not present a cold metallic surface in condensing the moisture of the air, but'will be adapted to absorb same, thereby preserving the grain or other produce that is close grain or the like when stored in thecrib more uniform with respect to ventilation and dryness andto prevent unduespoilage thereof immediately j t-to or ineontact with the ventilator pipe,

I attain these and other objects by the construction of a corn-crib or the like as is illustrated in the accompanying drawings in which Fig. 1 is a longitudinal or elevation view of the ventilator pipe, showing the preferred construction thereof.

Fig. 2 is a side elevation of a crib or the like having a portion broken away to show the arrangement of a plurality of ventilator pipes extending through the roof of the crib or the like, with ventilators attached thereto in spaced apart relation.

Fig. 3 is a perspective view of the ventilation pipe.

It will be understood by those skilled in the art that the construction of the crib, and ventilator as shown in the drawings are illustrative only, showing the preferred embodiment of the invention. In the preferred embodiment of the corn-crib or the like a series of sections are provided which are attached and fastened together to provide the walls of the crib in any well-known manner such as spot-welding.

The sections 1 are preferably provided with a series of apertures 2 and having lips 3 pressed therefrom as more fully described and shown in patent to C. M. Rowland entitled Corn-crib No. 957,381 and hearing date of May 10, 1910.

The lips extend outwardly from the walls of the crib and protect same more or less from weather conditions such as snow, rain or the like.

The top or roof 4 of the crib is preferably made of the shape shown in the drawings and is attached to the walls of the crib in any well-known manner.

A ventilator pipe 5 made of wood is provided and supported upon the bottom of the crib 6. The preferred form of constructing the ventilator pipe is by arranging a series of wooden slats or the like 7 around circular members 8 and spacing same in spaced relation to each other to provide openings 9. The openings between the slats form a pipe or the like and are open up to the point indicated by reference numeral 10, which is in close proximity to the level of the bottom of the roof 11 as indicated by reference numeral 10. The openings from the point 10 to the top of the roof are preferably closed by a series of shorter wooden slats 12.

The ventilator pipe as will be noted will be closed from the point indicated by reference numeral 10 up through the top of the roof indicated at 13 and elbow 14. While the lower portion of the ventilator pipe is provided with openings as indicated by reference numeral 9.

A conventional form of ventilator 15. is attached to the elbow 14 to be operated by wind suction, wind pressure or by the change of temperatures of the heated air passing outward. The swivel mechanism of the ventilator is indicated by reference numeral 16.

The construction of a crib as hereinbefore described provides means for the use of wood as a material and construction of a ventilator pipe that does not produce the excessive moisture that is ordinarily condensed on a metal ventilator. The moisture is not condensed as readily on ventilator pipes made of wood or the like as would be the case in the use of cold metallic surface or a metal ventilator pipe hence, the flow of air ventilates and dries out the corn in the crib uniformly from the walls of the crib to the ventilator pipe.

The use of wood for a ventilator absorbs more of the moisture condensed from the air than can possibly be absorbed from a metallic ventilator pipe and the temperature surrounding a ventilator pipe made of wood would be warmer than it would be if the ventilator pipe used was made of sheet metal.

Attention is further called to the fact that the grain or the produce in the crib will be better preserved and be kept in a better state, that is; it will be drier, better ventilated, excessive dampness will be prevented and other deleterious effects such as molding and the like eliminated.

The closing of the top of the ventilator pipe at a point near the bottom of the roof and the tight closing of the roof prevents drafts therefrom and forces the air by natural process to permeate through and ventilate the corn uniformly and the use of a wood ventilator eliminates the excessive condensation of a metal ventilator.

A crib or the like constructed and arranged for curing produce and using the process described, provides eflicient means to attain the objects sought to be obtained which are simple in construction, prevents unusual condensation due to the use of a metallic ventilator pipe thereby preventing spoilage of the contents of the crib or the like.

The gist of the invention consists in constructing a crib or the like for the storing of grain or the like in which the upper portion excludes the air, having no openings or apertures in the upper portion, except a ventilator and by providing a ventilator pipe of such material as will be moisture resisting, preferably of such wood as white pine or cypress.

It is not the intention to confine the present invention to the type of crib shown as changes and alterations may be made in the structure without departing or deviating from the spirit of the invention.

I claim: 7

In a sheet metal crib for storage of grain or the like, a body having a series of ventilating openings formed around the body, means for partially closing the ventilating openings, ventilating means composed of wood positioned in the center of the crib and spaced apart to absorb moisture and condense same,

the ventilating means permitting air to enter, means for holding the absorbent material together, said ventilating means comprising a plurality of Vertical slats positioned in spaced apart relation at the bottom thereof, the spaces being closed at the top by a plurality of slats from a point substantially adj acent to the horizontal plane of the eave of the crib and extending to the apex of the roof of the crib and auxiliary Ventilating means secured thereto.

In testimony whereof I afiix my signature.
